A fine orthoclase feldspar crystal from Balfour Downs Station, Pilbara region of W.Aust. A wonderful specimen of razor sharp orthoclase crystal It is in perfect condition, in hand the specimen is even more smooth and well defined! Excellent crystal formation, these old specimens, (probably more than 60 years out of the ground) have little competition when it comes to fine Australian orthoclase crystals. This is the last one of these fine orthoclase crystals we have. Ex Tony Forsyth.
